BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a collapsible Christmas tree, especially to a collapsible Christmas tree that is easy to be assembled and has a reduced volume when folded.

2. Description of the Prior Arts

Christmas tree is a common decoration during the Christmas season. Traditionally, people set up an evergreen tree, such as pine, at home, and put multiple string lights and colorful decorations on the tree.

However, the conventional Christmas tree is often a real tree. Real trees cannot be disassembled and folded, such that the conventional Christmas trees cannot be reduced in volume, which makes a lot of inconvenience for storage before sale or for transportation.

To overcome the shortcomings, the present invention provides a collapsible Christmas tree to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a collapsible Christmas tree that is easy to be assembled and has a reduced volume when folded.

The collapsible Christmas tree has a main trunk, a base, and multiple string lights. The main trunk is telescopic. The base is detachably mounted on a bottom end of the main trunk. The string lights are connected to the main trunk and the base. Two ends of each string light are respectively connected to a top end of the main trunk and the base. The collapsible Christmas tree as described is artificial, such that the main trunk and the base can be disassembled from each other. Additionally, the main trunk is telescopic, which further reduces the overall volume when the collapsible Christmas tree is folded. As a result, the collapsible Christmas tree is convenient both for storage and transportation.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIG. 1, a collapsible Christmas tree in accordance with the present invention comprises a main trunk 10, a base 20, and multiple string lights 30.

With reference to FIGS. 2 and 3, the main trunk 10 is telescopic.

With reference to FIG. 1, the base 20 is detachably mounted on a bottom end of the main trunk 10.

The string lights 30 are connected to the main trunk 10 and the base 20. Each string light 30 has a top end and a bottom end. The top end of the string light 30 is connected to a top end of the main trunk 10. The bottom end of the string light 30 is connected to the base 20.

The components mentioned above can form a shape resembling a Christmas tree. When the collapsible Christmas tree is for storage before sale, the main trunk 10 is disassembled from the base 20, and the telescopic main trunk 10 is retracted to a shortest length. Then, the folded Christmas tree is convenient for pre-sale storage, and is also convenient for transportation after the user purchases the Christmas tree.

With reference to FIGS. 4 and 5, in a preferred embodiment, the main trunk 10 has a bottom tube 11, a middle tube 12, and a top tube 13. The middle tube 12 is moveably mounted in the bottom tube 11. The top tube 13 is moveably mounted in the middle tube 12. Thus, the main trunk 10 can be retracted in two stages.

The bottom tube 11 has a top hole 111 formed through the bottom tube 11 and is adjacent to a top end of the bottom tube 11. The middle tube 12 has a top hole and a bottom hole 121. The top hole and the bottom hole 121 are formed through the middle tube 12. The top hole and the bottom hole 121 are respectively adjacent to a top end and a bottom end of the middle tube 12. The top tube 13 has a bottom hole formed through the top tube 13 and is adjacent to a bottom end of the top tube 13. The main trunk 10 further has a middle resilient element 14 and a top resilient element.

The middle resilient element 14 is mounted in the middle tube 12 and has a middle protrusion 141. The middle protrusion 141 is formed on an end of the middle resilient element 14, is mounted through the bottom hole 121 of the middle tube 12, and selectively engages the top hole 111 of the bottom tube 11. Therefore, when the middle tube 12 extends out of the bottom tube 11, the middle protrusion 141 is mounted through the middle tube 12 and the bottom tube 11 to keep the middle tube 12 in position. After pushing the middle protrusion 141 into the middle tube 12, the middle tube 12 can be received into the bottom tube 11.

The top resilient element is mounted in the top tube 13 and has a top protrusion 151. The top protrusion 151 is formed on an end of the top resilient element, is mounted through the bottom hole of the top tube 13, and selectively engages the top hole of the middle tube 12. Therefore, when the top tube 13 extends out of the middle tube 12, the top protrusion 151 is mounted through the top tube 13 and the middle tube 12 to keep the top tube 13 in position. After pushing the top protrusion 151 into the top tube 13, the top tube 13 can be received into the middle tube 12.

With reference to FIGS. 4 and 6, the base 20 has a main rod 21, a screw 24, two minor rods 22, two resilient sheets 25 and four surrounding rods 23. The main rod 21 has a connecting tube 211. The connecting tube 211 is formed on a center of a top of the main rod 21, and is mounted in a bottom end of the bottom tube 11 of the main trunk 10. The screw 24 is mounted in and screwed into the bottom tube 11, and abuts against the connecting tube 211 to connect the main trunk 10 and the base 20 together. After disassembling the screw 24, the main trunk 10 and the base 20 can be disassembled from each other.

The main rod 21 has two connecting segments 212. The connecting segments 212 are respectively formed on centers of two opposite side surfaces of the main rod 21, and are respectively mounted in inside ends of the minor rods 22. The resilient sheets 25 are respectively mounted in the connecting segments 212. Each resilient sheet 25 has a sheet protrusion 251. The sheet protrusion 251 is formed on an end of the resilient sheet 25, and is mounted through the corresponding connecting segment 212 and the corresponding minor rod 22, thereby connecting the main rod 21 and the minor rod 22 together. After pushing the sheet protrusion 251 into the connecting segment 212, the main rod 21 and the minor rod 22 can be disassembled from each other.

With reference to FIG. 7, the main rod 21 has two sleeves 213 respectively formed on two ends of the main rod 21. Each minor rod 22 has a sleeve 221 mounted on an outside end of the minor rod 22. Two ends of each surrounding rod 23 are respectively mounted in the corresponding sleeve 213 of the main rod 21 and the sleeve 221 of the corresponding minor rod 22. Each surrounding rod 23 is clamped securely between the main rod 21 and the corresponding minor rod 22. The bottom ends of the string lights 30 are connected to the surrounding rods 23. After disassembling the minor rods 22 from the main rod 21, the surrounding rod 23 can be easily disassembled.

With reference to FIGS. 1, 2 and 8, the main trunk 10 further has a connecting loop 131. The connecting loop 131 is connected around an outside surface of the top tube 13, is adjacent to a top end of the top tube 13, and is connected to the top ends of the string lights 30. The string lights 30 are annularly arranged at intervals around the main trunk 10. The collapsible Christmas tree further has a star decoration 40 detachably mounted on the top end of the top tube 13.

With reference to FIG. 9, the collapsible Christmas tree as described can be disassembled into multiple components, and the main trunk 10 can be retracted in two stages. Therefore, a rectangular box 50 can accommodate the components, thereby reducing the overall volume for convenience for storage and transportation.
